But if you’re in the majority of people who are both angry and frustrated with conflicting health information, Robert Davis steps in here to help.

The introduction of his book, Coffee Is Good For You, breaks down why there’s so much confusion as to what is good or bad for you, then goes on to explain how the scientific method fits into nutrition studies. For example, different kinds of studies are more reliable than others, and you should always look at who’s funding the studies, and whether or not they had any say as to what goes on in them. A lot of people skip over the introduction of most books, but this one is definitely worth your time!

After the introduction, we get to the meat of the book. Each chapter is divided into categories of nutrition claims (fats, sugars, diets, etc), then broken down further into a specific claim, which is marked as yes, no, half-true or inconclusive, followed by the findings of pertinent studies. If this all sounds very dry, don’t worry: Davis is extremely good at dropping bits of trivia and humor to keep you interested in what’s being said.

Once you’ve read Coffee Is Good For You, just make sure you can soften your know-it-all response of, “Actually…” when someone inevitably recites scraps of flawed information.
